A lever 40 has a sleeve portion 41 which i receives an axle 42 having the ends thereof within the lthe plates from the'pan.

mounted in the rear portion 'of the plates 36 and. 37 A portion of the lever adjacent the sleeve 41 is curved downwardly as shownat- 43 in order lto provide a means for engaging the rear flange 11 of the pan`10 and this flange acts as a fulcrum when the lever` is swung outwardly7 and downwardly for elevatingA the rear ends of the plates 36 and 37.

Transverse grids 45 are located in the pan and these grids are provided with slots 46 to receive plates 36 and 37. A portion 47 of the transverse grids 45 are located below the slots 46 and connect the sections of the trans- It will be noted from tion as shown verse grids together. Figure 4 that the plates along the lower edge are provided with notches 48 into which the connecting portions 47 are adapted to seat when the plates are in the operative position pan 10. The opposite faces of 36 and 37 along the lower edges as .shown at 49 are engage the lower edges ofthe cubes of ice for aidig in lifting the ycubes after the cubes have been broken away The opposite faces of the plates are lo- .cated i'n parallel relation. However, Athe cengitudinal edges ofthe pan and Vtral partition 50 of the grid has its side walls inclined at an angle so that the lower portion of the partition 50 is wider .than the upper.

thereby reducing the lower portion of the cubes which willfacilitate the removal of lthecube's.

`The artitionl 50 is secured tothe transverse .p ates -45 and is removable as a unitk with .the transverse plates. Lugs v52 are secured to the flange 11 along the opposite lonthese lugs project inwardly having a reduced free portion 53 which is adapted to be seated within complementary formed notches 54 in the opposite ends of the transverse 52 fit in the notches .and .aidin maintaining the transverse plates in position. It will be noted, however, 50 is of less length than the lengthv of the inner portion of thepan so lthat the partition may be shifted longitudinally of the .pan for releasing the lugs 52 from the notches 54 in the transverse plates 45.' When this occurs the grid formed on the central partition 50 and the transverse plates 45' maybe removed bodily from the pan.

It will be noted that the notches 48 and the connecting portions 47 are complementarily formed in order to provide a neat fit between the plates 30 and 37 andthe transverse grid plates 45.

In the modified form-in Figs. 7 and 8 the central plate is omitted. However, a plate is secured to the transverse grid plates 61 and Alower edges of provided .with laterally projecting lugs which y37 and is plates 45. The lugs that the central partition nally of the ment lwith the flange,

*is norm-ally in flat contact with the inner face -of the longitudinally .disposed plate' 36a. This lconstruction providesfor the reduction of the water chamber which runs centrally andlongitudinally of the pan. The inclined sidewalls ofthe pan 10 cooperate with the plates 36 and 37 to reduce the water charnbers upon opposite sides of t-he pan.

.The plate 36 is provided with a plurality of lugs or projections 49 which engage the the cubes aiding in elevating the cubes when the plates 36 and 37 are raised. The plate 37, however, has spaced lugs 49 upon opposite faces and .these lugs yrest upon the bottom 62 of tle pan.

The remaining portions of thepanand the grid sectionas well as the operating means orthe grid section are identical in construcin Figures 1 to inclus'ive.

The operation of my device Eis..as'f'follows: TheV grid section consisting of plates 36'and 737 are positioned within the pan lfas shown approximately horizontal position. The lip 35 is secured 'ltothe ends of the plates 36 and inthe position shown .in Figure 3.

The 'pan is Vfilled with `water l.and is`-placed within the refrigerator.

When the water is frozen and the cubes have been vformed itis only necessary to rotate the-"handle26 whereby the gears 19 and 18 will be revolved causing the member 32 to be moved upwardly with the lug 33. As the member 32 is moved :upwardly the lip 35 is likewise forced upwardly and thereby .ele- Y vates the inner end of .the l.plates y36 fand 37. The lever 40 is :then thrown upwardly and 'outwardly and as the y:portion 43 engages the flange 11 and the lever is forced downwardly the lrear portions -ofzthe plates 36 and 37 will be elevated. When this is done the cubes will be broken away from the walls of, the transverse plates 45 and Ielevated with the plates 36 and 37 due tothe fact that `the lugs 49 engage the-bottoms of the cubes.

The inclined side walls of the pan 10 and the inclined wallsof .the -central partition 50 facilitate the removal of the cubes.
